WELL CABLE-PUMP.

To all whom it may concern Be it known that 1, Jon N. FENDER, a citizenof the United States, residing at Dallas, in the county of Dallas andState of Texas, have invented a new and useful llvell Cable-Pump, ofwhich the following 1s a specification.

This-invention relates to an improved pump and more particularly tooneadapted to be used in connection with deep wells for pumping oil orother fluids and the; ob ect thereof is to provide an improvedconstruction whereby it will obviate the necessity of employing a longline of extra pipe and the usual pump rod which gives so much trouble.

A further object of the invention is to provide an improved pumpemploying a cable in lieu of the ordinary pump rod, and which includes anovel construction of pump device facilitating the pumping operation,and also the removal of the parts for cleaning or repair or any othercause.

ll'ith the above and other objects in view which will appear as thedescription pro ceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that within the scope of whatis claimed, changes 1n the precise embodiment of the inventlon shown,can be made without departing from the spirit of the invention.

In the accompanying drawings Figure 1 is a vertical sectional view ofthe upper portion of the pump;

Fig. 1 is a similar view of the lower portion of the pump;

Fig. 2 is a sectional view taken on the line 2-2 of Fig. 1 7

Referring to the drawings in which like reference characters designatesimilar parts throughout the several views, the numeral 10 designates awell casing'which is driven into the ground at a suitable depth so as tostrike a subterranean stream or supply of fluid, such as oil, water orthe like. The casing is shown extended to the cap rock 11,

'of the stream 12, from which the fluid supply is drawn. hlountedin thebott0m of theicasing is a perforated strainer or suctlon pipe 13 whichis connected at itsupper end tothe lower end'of the cylinder or workingbarrel 141 by a pipe coupling 15, preferably internally threaded toengage the corresponding external threads of the ad acent ends of thepump cylinder and suction pipe;

Specification of Letters Patent;

Thepuinp cylinder or working barrel-ex tends upwardly at a'suitabledistance, and has the upper end thereof provided with a reducedperforated swage nipple-16,. the perforations below said nipple orswaged portion being indicated at 17 in the tapering Patented July 27,1920.

or. conical upper end of the pump cylinder or working barrel, so as toreceive the short section or pump rod 18 therethrough. Said pump rod ismade in a. series of sections the lowerend of-which is connected by acoupling 19 with, a suitable valved pump plunger 20 having the usualpassage 21 therethrough, and the cage 23 mounted on the upper endthereof to retain the ball.

valve 24. in position, saidv ball being designed to open on the downwardstroke of the plunger and to, close on the upward stroke of the plungerso as to lift the fluid within the pump: cylinder or workingbarrel.

The connection of the pump rod is made with a reduced extension 25extending from the upper end of the cage, the coupling preferably beinginternally threaded for engagement with the corresponding externalthreads of the pump rod and the extension 25 as clearly. shown in Fig. 1of the drawing. r

Mounted in the lower end of the pump cylinder or Working barrel abovethe perfo rated suction pipe 13, isa valve member, 26 v the same havinga cage 27 on the upper end thereof which retains a ball valve 24, ex-.cept that the ball: valve 28 is-open 'on the upward stroke of the:plunger 20 and closed on the downward stroke thereof in oppositerelation to the operation of the ballvvalve 24, thus providing one ofthe valves to supportor maintain the column of liquid within thepumpcylinder or working barrel and the casing, atall' times.

Above the coupling 19,. is disposed a similar coupling 29 which islimited in its upward movement by the nipple 16 and which also permitsseparation of the parts for the pu-rposeof cleaning or repair and alsofacilitates assemblage thereof. The pump cylinder or working barrelcarries externally below the nipple 16, a supporting collar or seat 30having an enlarged upper end portion providedwith a suitable leatherpacking collar or washer 31 seated therein, and forming a water or fluidtight connection with the lower end of a pipe section 32 which. fitsover the working barrel at the upper end thereof and is provided at itsupper end, with a swaged nipple 33 beneath which said pipe is taperedand provided with suitable apertures 3 L for the escape of the fluidtherethrough. There is provided between the,

nipple 16 and the nipple 33, a coupling 35 similar to thecouplinsrs-lQand329, the coupling 35 being limited in its upward movement by thenipple 33,"although the short sectional pump rod or shaft'18, com-,

prising three sections as shown, extends through the nipple 33 andconsiderably abovethe same for connection with a cable 36 which'isemployed in lieu of the usual pump rod, thereby permitting the cable tobe wound upon a suitable drum for raising the parts, while permittingreciprocation of the plunger in theusual or any preferred manner. Theconnection of the pump rod with the cable is made through the medium'of-a coupling 37 andsuitable clamps 38 anchoring the extremityof thecable above the coupling, which latter is'preferabl'y provided with athreadedsocket in its lower end to whichthe upper endvof the pump rod isconnected as shown at 39,'said ends being externally threaded for thispurpose.

' The lower end of this pipe or outer work'- ing barrel or pumpcylinder'32 rests upon the collar in engagement with the packing washer31, immediately above which the pipe 32 is'provided with a series ofapertures 40.7 Aboveand below the apertures or openings 40 in the wallof the pipe 32, there 7 are disposed collars or'lock nuts 41 betweenwhich are'clamped an annular leather or V rubberpacking sleeve 4i2 whichfits against 1 the interior wall of the well casing.

V In theloperation of the device, it should b'e'noted that there isslight space between pump cylinder or working barrel 14 and the outerpump cylinder or working barrel mountecb'above and over the same andformed 'by the pipes 32, so that as the plunger is reciproeated, thefluid such as oil, when the device isfused in connection with an oilwell, will be caused to pass successively'by'the valves '28 and 24 andabove the plunger, being prevented from passing downwardly by saidvalves when in closed positions, but beingeifectivelystrained in'passing through the perforated suction pipe 13. This prevents entranceof foreignmatter to the pump and as the fluid 'islifted, it

will pass out through'the openingsl'? from the pump cylinder or workingbarrelinto' the outer or upper pump cylinder or working barrel 32 orpipe formingithesame, and then 'passthrough the openlngs 34to be liftedin the wellcasing to be discharged. However,"acertain amount of fluidafter passing through the openings 17 will pass between said cylinders14 and 32, and enter the space between the same through theopenings '40behind the packing sleeve 42 and being forced outwardly under thepressure, caused by the fluid or oil, will seal it against the casingand make a perfect fluid tight oint which will prevent the fluid fromcharged from the top of the casing and should it be desired to pull thepump for any cause, itwill'be simply necessary to wind on the cablewhich will cause the coupling 35 to strikeythe nipple or sleeve 33,

thuslifting the pipe or outer pump cylinder 32 from its seat uponthe'washer 3l-of the collar30, thus relieving the'pressure and a1-lowing the fluid to be discharged downwardly into the casing around thecollar 30 and further permitting the coupling 29 to engage the "nippleor sleeve 16 and to raise the working valve and parts associatedtherewitli,:as soon as the head of oil above the "valve is relieved} theplunger moving upwardly with the rodrduring this opera- 'tion,andthereby permitting the pump to be drawn out.

Having thus fully described "my invention, what claim is: V
